Identification of a coproporphyrinogen-III oxidase gene and its correlation with nacre color in Hyriopsis cumingii
Pearl color is an important factor influencing pearl value, and is affected by the nacre color of the shell in Hyriopsis cumingii.Coproporphyrinogen-III oxidase (CPOX) is a key enzyme in porphyrin synthesis, and porphyrins are involved in color formation in different organisms, including in the nacre color of mussels.In this study, a CPOX gene (HcC
